Each year, LCS Laboratory analyzes approximately 20,000 samples of construction materials for asbestos contamination. These materials include flooring, drywall, joint compounds, ceiling tiles, pipe insulation, attic insulation, and other building products commonly found in older structures.
This page is a structured FAQ index with links to detailed articles covering key aspects of asbestos testing, sampling, and regulatory considerations.
- What materials should be tested for asbestos?
Test any material that will be cut, drilled, sanded, or otherwise disturbed during renovation or demolition. Asbestos-containing materials are generally not hazardous if left undisturbed. Common examples include vinyl flooring and drywall joint compounds. A more comprehensive list is available on this page. - Why is asbestos hazardous?
Disturbing asbestos-containing materials (ACMs) releases microscopic airborne fibers that can be inhaled and accumulate in the lungs over time. - Which construction materials may contain asbestos?
An illustrated list of potentially asbestos-containing materials is available here. - Which materials typically do not contain asbestos?
Based on laboratory experience, asbestos is not typically found in wood, steel, glass, red brick, or porcelain. - Until when was asbestos used in construction?
In most residential construction, asbestos use declined significantly by the mid-1980s. For Ontario-specific context, refer to this article. One notable exception is vermiculite insulation, which may be present in newer homes. - How much sample material is required for analysis?
Most materials require only a small quantity (approximately a teaspoon). Vermiculite insulation typically requires a larger sample (approximately one cup). Additional details are provided in this article. - How many samples of the same material should be tested?
In many cases, three samples of the same material are recommended to demonstrate that it is asbestos-free. In some situations, a single sample may be sufficient. See this article for detailed guidance and regulatory references. - What is the cost of asbestos testing?
Current pricing for different testing services is outlined here. - What is the cost of vermiculite testing?
Please refer to this page for pricing details. - How long does it take to receive results?
Standard turnaround time is within 7 business days. Expedited options may be available. - Where is the laboratory located?
The laboratory is located in London, Ontario, Canada. Full address, map, and directions are available on the Contact Us page. - Can I deliver samples in person?
Yes. Step-by-step instructions are available on this page. 
Additional details, including the sample drop box location, are provided on the Contact Us page.- Can I speak with laboratory personnel when dropping off samples?
Yes. Please use the courtesy phone in the building lobby and call 1-(519) 777-5232. A staff member will meet you in the lobby. For safety reasons, access to the laboratory is restricted. - How should samples be packaged for shipping?
Place the sample in two sealed zip-top bags or a rigid container. Ship it in a box or padded envelope. Avoid using paper envelopes, as they may tear during transit. Additional guidance is available here. - How do I send samples from within Canada?
Shipping instructions are provided on this page. - How do I send samples from the United States?
Please refer to the international shipping instructions. - How can I pay for testing?
An electronic invoice will be issued upon sample receipt for online payment by credit card. Interac e-Transfer is also accepted. Cash payments and mailed money orders are available as alternative options. - How will I receive the test results?
Results are delivered by email. - Can I review a sample report?
An example report, along with explanations of technical terms, is available here. - Will the report include the percentage of asbestos?
Yes. Reports include both the concentration and the type of asbestos identified. - What is a “safe” asbestos level?
The term “safe” is often misunderstood. Regulatory limits are more appropriate for decision-making. In Ontario, the current threshold is 0.5% (2024). See this article for clarification. - What if my sample has multiple layers?
Each layer should generally be analyzed separately. Additional information is available here. - Are test results confidential?
All results are treated as confidential and are shared only with the client. Disclosure would only occur if required by a legal order. - Will third parties accept the laboratory report?
Most contractors, consultants, and agencies accept standard laboratory reports. However, some organizations may request specific providers. To avoid delays, you may review a sample report in advance: 2020 Asbestos report.
